Barry Rose Wastewater Treatment Plant Rehabilitation

Pearland, Texas

Scope covered rehabilitation and improvement of the existing wastewater treatment facilities including bar screen, conveyor, demolition of the existing sand filters to install Disk-filter systems, removal of the abandoned thickener mechanism to install a new bridge-supported sludge thickener; replacement of the broken centrifuge unit with a new centrifuge system; upgrade of the plant-wide SCADA system; rehabilitation of existing motor control center and electrical transfer station,  

Remove the existing sand filters to install two Disk-filter systems with smaller foot print and increased filter capacity. Reuse the abandoned clarifier structure to install a new bridge-supported sludge thickener mechanism with new aeration equipment, saving at least $400,000. Replace the broken centrifuge with an energy-efficient centrifuge system including new controls, saving electricity cost and polymer consumption. Barry Rose WWTP Rehabilitation was awarded TPWA Project of the Year, 2014.

1. convert the abandoned clarifier into a sludge digester and thickener with external structure support for the thickener mechanism and use air lift pump to discharge thickened sludge.
